Micopolarization elements on p-aminoazobenzene film induced by femtosecond laser pulses

  • 摘要: 用400 nm和800 nm线偏振飞秒激光垂直聚焦于对氨基偶氮苯薄膜表面上,以形成纳米微结构.实验观察到400 nm和800 nm线偏光照射样品表面分别得到周期为210 nm和500 nm的干涉条纹,条纹周期均随激光能流密度的增强而增大.通常认为这种周期结构是由入射激光与材料表面的散射光相干涉所形成的:光的干涉引起材料表面温度呈现梯度变化,从而引起表面张力呈现梯度变化,诱导周期条纹的产生.制备偶氮聚合物的厚膜,用400 nm飞秒激光照射样品表面,同样也得到周期性纳米微结构.
